Application Notice: Major Financial Institution Installs Battery Room H2 Monitoring Systems to Comply with Safety Regulations

Battery Room Hydrogen Monitors for NFPA 111 Compliance

Remote Sensor Mounting KitApplication: Battery Room Hydrogen Monitoring Industry: Financial Institution / Office BuildingResults Achieved:

Installed Hydrogen Monitoring System with Supervisory Notification •

Integrated Hydrogen Monitoring System to Building Ventilation to Meet • Regulatory Building and Safety Code

Reduced Insurance Costs•

ApplicationA Major financial institution upgraded their data center battery rooms for reliability, safety, and compliance with local building codes and NFPA 111.

ChallengeBattery rooms at the financial institution had grown piecemeal as the data centers expanded. Safety systems were either nonexistent or inadequate to serve the larger stored energy capacities now present.

Newer stored energy system requirements force UPS users to upgrade existing battery rooms for compliance with local fire and building codes and NFPA 111, “Standard on Stored Electrical Energy Emergency and Standby Power Systems.”

During charging, lead acid batteries discharge Hydrogen that ignites easily and explodes when present in high concentrations. A Hydrogen flame is invisible and fires are extremely hazardous to personnel.

The bank required reliable Hydrogen detection to satisfy their insurance company and comply with NFPA 111, referenced in the local fire and building codes.

SolutionA Sensidyne SensAlarm Plus gas monitoring system was installed with Hydrogen specific gas sensors. Ceiling mounted remote sensor heads monitored the lighter than air Hydrogen while the SensAlarm Plus enclosure was installed outside the entry door. The gas detection system integrated with battery charging equipment and ventilation fans. Installation was simplified due to easily remote mounted sensor heads that only required a 4-conductor cable connection.Refer to NFPA 111 “Standard on Stored Electrical Energy Emergency and Standby Power Systems” and NFPA 70 “National Electrical Code” for additional Battery Room safety information.

The Advanced All-In-One Gas Detection System

SensAlarm Plus is a complete gas detection system in one enclosure. The system is fully equipped with strobe, horn, high-visibility four-digit LED Display and LCD Display / Interface. At the core of SensAlarm Plus is an advanced Intelligent Sensor platform with non-volatile memory for all key application variables and sensor data. A non-intrusive user interface enables operational customization and access to sensor life parameters, TWA alarms, calibration data and other information with date and time recording.

The SensAlarm Plus sensor head is universal in that it accepts all Sensidyne Plus sensors. Monitoring in high, low or adjacent locations is simplified by remote mounting the sensor head using 4 conductor cable. The automatic uploading of variables, alarm values and sensor information when a sensor is plugged in greatly simplifies installation and maintenance. Transportable calibration allows sensor calibration at the point of installation or in a workshop, then hot-swapping the sensor in the field.

SensAlarm Plus is the ideal gas monitoring solution for labs, gas cylinder storage, industrial work areas, control room protection or any other applications where users benefit from a packaged gas detection system that works with all SensAlert Plus sensors.
